10.

A researcher conducted an experiment to test whether sleeping immediately after learning improves memory of the learned information. On the first evening of the experiment, volunteer non-Spanish-speaking participants were required to learn a list of Spanish words. They were then allowed to sleep for an hour. On awakening, they were asked to recall as many of the words as they could. On the second evening, the same participants learnt a new list of Spanish words. They then watched a television program for an hour, after which they were asked to recall as many of the words as they could. The research design of this experiment is best described as
- A.
  
  Repeated-measures
- B.
  
  Independent-groups
- C.
  
  Mixed-participants
- D.
  
  Matched-participants
11.

In a subsequent experiment investigating the effect of sleep on learning, half of the participants attempted condition 1 on the first day (sleeping after learning the Spanish words), then condition 2 on the second day (watching television after learning the Spanish words). The other half of the participants attempted condition 2 on the first day, then condition 1 on the second day. The experimenter used _____ to control _____ .
- A.
  
  Order effects; counterbalancing
- B.
  
  Counterbalancing; order effects
- C.
  
  Single-blind; order effects
- D.
  
  Order effects; confounding
12.

- C.
  
  Make more errors on complex or interesting tasks
- D.
  
  Make more errors on simple, boring tasks

- D.
  
  NREM stage 4
14.
